Using Perlin Noise correctly with varying "seeds"?
Basically I wish to use Perlin Noise, thanks to BlueTaslem, for terrain generation using bricks. Below is the script.
Since I'm not experienced with Perlin Noise, I decided to look into it a little, but didnt find much that I understood, nor how to use correctly. So any assistance with changing the values slighty and getting more "biomes" would be appreciated.
If you don't want to write code for me that's fine, I just want guided on the right path :)
local worldX = 100
local worldZ = 100
local blockWidth = 2
local blockHeight = 2
local model = Instance.new("Model")
model.Parent = game.Workspace
model.Name = "TerrainParts"
for _, obj in pairs(workspace.TerrainParts:GetChildren())do
if obj:IsA("Part") and obj.Name == "TerrainBlock" then
obj:Destroy()
end
end
function height(x, y) -- The Spot That Uses Perlin Noise
return (math.noise(x/20, y/20) + math.noise(x/35, y/35) + math.noise(x/77, y/77)) * 10 + 10
end
for x = 0, worldX, blockWidth do
for z = 0, worldZ, blockWidth do
local brick = Instance.new("Part")
brick.FormFactor = "Custom"
brick.Anchored = true
brick.Size = Vector3.new(blockWidth, blockHeight, blockWidth)
local y = math.random() + 4
brick.Position = Vector3.new(x, height(x, z), z)
brick.BrickColor = BrickColor.Green()
brick.TopSurface = 0
brick.Name = "TerrainBlock"
brick.Parent = game.Workspace.TerrainParts
wait()
end
end

I've not done much with biomes before, but I think this will work. I've made it so that you can easily add in/remove different biomes. If you wanna add in another biome, just add in another table inside the biome table, with the first value being the brick color, and the second one being the material. The actual use of the biome is very simple, and I hope will be easy for you to change, if needed. (as the biome selection I presume is more important)
